This paper is a presentation of a theoretical and experimental analysis of supply air jet flow patterns in a mixing ventilation system. Investigation procedure aims at reducing draft risks.
The paper presents the results of experimental tests : the enclosure size and background turbulence in the surroundings of the jet have an influence on the air velocity distribution in axisymmetric jets
Measurements and CFD simulations are compared for 4 different ventilation systems using the air change index and a new ventilation parameter. It is shown the advantage of impinging jets
The paper deals with the CFD analysis performed for a family house residence, which is in the design phase : the aim was to test several concepts for heating ( floor heating, floor convectors, both systems) in terms of thermal comfort.
This paper deals with an approach to a multizone airflow analysis that can account for mechanical energy conservation. It is shown that the resistance (dissipation) provided by zones in a multizone analysis should not be ignored.
This paper presents a universal but simple mathematic model very useful to predict Volatile Organic Concentration in the bulk air for different conditions in residential buildings.
This paper presents a numerical method aiming at recreating the concentration field of a pollutant at each point of a ventilated enclosure that contains one or several pollutant sources of unknown emission rate.
This paper deals with a 3D numerical study to assess the effectiveness of a displacement ventilation system to remove particulate pollutants, generated in the occupied zone of a room.
In this study, an office with mixing ventilation is considered. The CFD analyses show that for high cooling loads it is useful to couple a cold ceiling to primary air system
